Hm...I suppose at least he found out the true nature of the girl he liked, so that he could sort of move on with the girl who, well, sort of teases him all the time, but probably actually likes him.
Considering that ending, well, I'd say he actually lucked out.

I personally wouldn't say this is "fendom"; rather Kisaragi is more of "an assertive girl". Still, she seems to have taken a liking to Kiriyama ... only a continuation might confirm where things may go from here.
